Shorin ryu has katas with similar names to the Shotokan kata I was taught. Goju is different. I don't know if the Shorin kata are actually the same as the shotokan ones because I've never studied Shorin ryu,

The real tragedy is going to be when she grows up if she ever gets into a situation where she could defend herself or run and decides to throw her chips in with her 4 blackbelts she got when she was ten. Otherwise, who cares how old she is? If she did the work required for the belt to the standards of the testers who are we to say she doesn't deserve it? Quite often, black belt != martial arts badass.
